MULTIPLE-SECTION GRAIN DR LL.

Application filed January 8,1925. Serial No. 1,219.

In endeavors to employ more than one grain drill, the drills have been disposed one behind the other and connected in any suitable manner, one operator manipulating both drills. The objection to this method of operating more than one drill at one time is that difficulty arises in not being able to observe whether or not the rear drill is seeding properly or as to whether there is any trash, such as straw or weeds, entangled with. the rear drill. If there is any ti'asln this method of working two drills makes it difficult and very inconvenient to dismount the forward drill and run back and kick out the trash and while the operator is dismounted to observe whether or not the rear drill 1s seeding properly.

with these objections and difliculties in mind, the present invention has for its purpose to provide an improved couplin'g'between two drills or drill sections, whereby the drills are in alignment side by side, so as to overcome the obj cot-ions above pointed out.

In carrying out this scheme, the invention further aims to employ at least two sixteen-hoe grain drills in alignment side by side, their adjacent ends being spaced seven inches apart. grain drills including sixteen hoes each with a coupling connecting them, it is apparent that the coupling may be usedwithany construction of grain drill wherein is einployed a solid axle extending from one end to the other of the drill for the reason that'when the two grain drills are connected or coupled, the driving axle of each receives power from the outside wheel.

Still another purpose is to provide a coupling consisting of a depending auxiliary frame carried by the frame o'f one of the drills and braced relatively thereto.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

.Fi. ure l is a rear view showing two grain drillg coupled, portions of the centralparts of both drills being cut away so that the drills may be illustrated on an enlarged scale in order to bring out the schemeof the invent1on.

WVhile employing two 7 Figure 2 is a plan view ofthe adjacent coupled ends of the two grain drills. a

Figure 3 is an enlarged detail perspective view of the two frames of the grain drills with the depending frame and the supportlanes? main section 5, which is approximately U- form in side view, and the auxiliarysection G. The latter sectionconforms to the contour ofthe main section 5 of the depending frame and has lateral angular ends? which are bolted at 8 to the main section.

Suitable braces 9 are secured at 10 to the auxiliary section of the depending frame and are bent or suitably formed to accommodate themselves for connection to the frame of the grain drill at the right. The braces 9 are secured at 11 to the grain'drill frame by suitable bolts or the like 12. Ad-

ditional braces 13 and 14, angularly vdisposed, connect the main section of thedepending frame and the front and rear bars of the frame of the grain drillto the right, suitable bolts or the like 15 being used to secure'the braces '13 and 14 in position.

, The bolts or other fastenings which secure the depending frame to theframe of the grain drill to the right and the bolts,

which secure the-braces 13 to the grain drill frame also act'to secure hinge members 16 to the grain drill frame. By means of suitable belts 17, additional hinge members 18 are secured to the frame of the grain drill to the left. A suitable pivot rod 19 passes through the adjacent overlying ends of the hinge members and has nuts or the like for holding the rod in place, thereby connecting the hinge members and hence coupling the twov grain drills relative 'tov each" other. A supporting wheel QO'carries the weight of the. mechanism below the hinge members. V I Y I I I This manner of coupling the two drills enables the drills to Operate: in alignment,v avoids the operator d1smount1ng and run- CTI ning to the rear to determine Whether or not the drills are seeding'properly and also obviates the collection of trash which usually results in an endeavor to operate one drill in the rear ofanother.

The invention having been set forth, what is claimed is:

The combination of a duality of axially aligned grain drills With the adjacent ends of their frames pivotally connected, supporting Wheels at thereniote ends of the frames of said grain drills, a depending frame consisting of a U shaped main'seotion secured to the frame of one of the grain drills, an auxiliary section spaced from the 1 main section but having angular ends bolted to the same, and braces secured respectlvely to the grain drill frame and said auxiliarysection, and a supporting Wheel disposed between the main and auxiliary sections of .20
